Plant Notes:Smooth Jointgrass is a native perennial warm season bunch grass in the Grass family (Poaceae). It is endemic to the Southeastern United States, and is found in Alabama, Florida, and Georgia. In Alabama it is found in the southern tier of counties along the Florida state line. Smooth Jointgrass grows in moist pine flatwoods, bogs, and seasonally wet depression ponds. It grows to a height of four to six feet, and the glumes on the sessile spiklets are smooth or slightly wrinkled. It is one of four species in the genus found in Alabama. They are distinguished mainly based upon characteristics of the sessile spikelets. Smooth Jointgrass is listed as an S1 plant in Alabama (typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology making it especially vulnerable in the state) and globally as a G3 species (imperiled globally because of rarity (6 - 20 occurrences, or few remaining acres, or miles of stream) or very vulnerable to extinction throughout its range because of other factors). It is not available from nurseries.--A. Diamond
